A drive coupling for transmitting rotary motion from an input shaft to an output shaft is provided. The drive coupling comprises a male member formed from plastic having a protruding flange, and a female member formed from plastic with a cavity shaped to accept the protruding flange of the male member. The male and female members are secured to the ends of the shafts to be coupled in such a manner that the protruding flange of the male member is fitted into the correspondingly shaped cavity of the female member whereby the members are joined such that rotary motion of one member is transmitted to the other member. Preferably, the male and female members of the drive coupling are made from polyurethane having a hardness of 80 on the Shore Durometer A scale.
