If Clarinetists sometimes need A clarinets for orchestral works, what do trumpets do? they don't make trumpets in A do they?

AFAIK there are trumpets in high Bb, A, G, F, Eb, D,
sopranos in C, Bb, A
bass trumpets in F, Eb. (stravinsky uses low Bb trumpet in The rite of the spring).
2 Brandenburg concert if for high F trumpet...

Just like clarinets, trumpets come in various keys. One can purchase a piccolo trumpet in Bb or A... generally, they make them in just about every key. Bb and C are the more common ones, D, F, G, E, Eb all exist, as well.
You can buy typical trumpets like you'd see in a basic band, piccolos, pockets, flugelhorns... all kinds of trumpets and variations in different keys.
try looking here at this address -- http://www.petrouska.com/TrumpetGuide.htm#Trumpet and Cornet
and searching for more about more information if you're interested.

At one time it was common for Bb trumpets (and cornets too, I think) to have a "rotary change valve" that put the instrument into A. The player would also need to pull the valve slides out a wee bit to keep the instrument properly tuned. Some horns still have a fifth valve that does the same thing, putting the Bb side into A and the F side into E, though horns need this for other reasons too technical to go into (okay, it's to do with hand-stopping, don't ask.)
This idea fell into disuse, on the trumpet at least, because playing in remote keys on a brass instrument is not a great deal harder than playing in "ordinary" keys. To finger a written C scale, sounding Bb on a Bb trumpet, the fingerings are:
C D E F G A B C
0pen 13 12 1 Open 12 2 Open
To finger a written B scale, sounding A on a Bb trumpet, and thus equivalent to a written C on an A trumpet, the fingerings are:
B C# D# E F# G# A# B
2 123 23 12 2 23 1 2
Some of the trills are more awkward in B than in C, but there are alternative fingerings to simplify some of them.

The trumpet rotary change valve reminds me of something I dimly remember from years ago;
Has anyone ever heard of a similar thing for the clarinet. A sort of double tube arrangement which when rotated realigns the holes to shift from B flat into A?

There's a picture of such a thing on plate 19 of Brymer's book.
This is similar to the trumpet's rotary change valve only in purpose, not in design. The trumpet thing is just an extra valve, built as a rotary valve rather than a piston, and activated by a handle that looks like a bath-tap. It doesn't do anything acoustically weird.
