ABSTRACT:
A coupling member for securing a spring to a rotatable motor shaft so that the spring rotates with the motor shaft. The coupler has a cylindrical hollow middle which fits snugly onto the motor shaft and includes a main body portion having a smaller cylindrically shaped nose portion extending therefrom for receiving one end of the spring therearound. The main body portion includes a ramp portion, extending upwardly therefrom, a wall behind the ramp portion and a slot therein for receiving a hook portion extending from the spring. The hook portion is snugly secured in the slot and behind the wall so that as the motor shaft rotates, the coupler member causes the spring to rotate with the motor shaft.
