The RH3 split D#-E trill key needs the ring of cork to keep the ring key at a specific height and isn't acting as a seal, so it doesn't really need to make full contact all the way around as a pad does against its tonehole.
Find the ideal thickness of cork so the ring key sits evenly around the inner bush (slightly higher than the bush, but evenly all round like a ring key should), then cut the appropriate diameter disc of that thickness cork (usually around 12.5mm) and punch out the centre (around 8mm) so it slips over the bush.
The best way to stick that on is apply contact adhesive to just the top side of the bush (once cleaned and degreased) and fit the cork disc while the adhesive is still fresh, using the outer ring to push it down.
That's probably the only time you'd use contact adhesive in this manner as opposed to using it in the proper way (applying to both surfaces and waiting for it to become touch dry before sticking both surfaces together).
It's not going to fall off as the central bush will keep it in place. The adhesive will go off in time, so it's not going to come adrift.
If the ring key is sitting at a funny angle in relation to the bush, then check the pad is sitting evenly in the pad cup (and reseat or change it if it isn't), then adjust the ring key so it also sits evenly when the ideal thickness of cork is placed between the ring key and the bush.
Ring keys on all woodwinds should always be even all the way around in relation to the tonehole chimney or bush they surround - the height of the ring key depends on the players hand and finger size and should be set up accordingly.
