Abstract
An input shaft to output shaft coupling including an input shaft having a first wave surface thereupon, wherein the first wave surface comprises mounds and valleys. The coupling additionally comprises an output shaft having a second wave surface thereupon, wherein the second wave surface comprises mounds and valleys. The coupling in one form additionally comprises a housing substantially enclosing the first wave surface and second wave surface, wherein rotational force exerted upon the input shaft is translated through the lobes of the first wave surface to the lobes of the second wave surface and to the output shaft in turn, and wherein the first wave surface and second wave surface transmit rotational force therebetween through any range of angles to a maximum output angle between a rotational axis of the input shaft relative to a rotational axis of the output shaft.
