Abstract: There is provided, for an appliance having an operating shaft with a non-circular end section, the control assembly which includes a drive means, a coupling member, and mounting means for mounting the drive means non-rotatably on the appliance. The drive means has a low-speed, high-torque output shaft, and the coupling member has a first opening to receive the operating shaft and a second opening aligned with the first opening, the second opening being engagable with the output shaft. The first opening is complementary to the non-circular end section of the operating shaft, whereas the second opening and the output shaft are engagable to provide a lost-motion connection that allows the output shaft to engage the second opening over a wide angular range while still allowing the output shaft to engage and drive the coupling member.
