It is a woodruff key. It is OS P/N 27708200, and it comes with the drive hub assembly, P/N 27708010.
I coverted a heli 50SX to aircraft use and OS sent me the part for free. They were really terrific about it.
You may be able to fashion it out of metal in the meantime, or an industrial supply place may have them.
Good luck.
