1. A rotational coupling device, comprising: a rotor disposed about an input shaft, said input shaft disposed about a rotational axis and said rotor and said input shaft defining opposed keyways; a key disposed within said opposed keyways of said rotor and said input shaft, said key rotatably coupling said rotor and said input shaft; an armature disposed about said axis, said armature coupled to an output member and configured for selective engagement with said rotor; and, a first support member disposed about said axis and configured to receive said key, said key separable from said first support member wherein said key and said first support member are shaped complementary to one another to limit radial movement of said key relative to said first support member in a first radial direction and in a second radial direction opposite said first direction and to limit axial movement of said key relative to said first support member in a first axial direction.
