The Cursed Ring of Hircine has a chance to trigger a transformation and according to the wiki page it only has a 10% chance to happen, i seem to remember on the two Werewolf playthoughs i did only on one of them did it actually trigger (and only once). You have to be a Werewolf first for it to actually happen and the ring has to be equiped.
