ABSTRACT:
A rotary control device which includes an output pulley housing and an output pulley rotatably mounted therein. A cable is at least partially wrapped around the output pulley and passed through a cable housing that is slidably mounted on the output pulley housing. The output pulley rotates in response to the movement of the cable. A spring mechanism is positioned between the output pulley housing and the cable housing to bias the pulley housing away from the cable housing to take up any slack in and tension in the cable. Furthermore, the output pulley or the input pulley or both can include a cam lobe or lobes formed on its periphery where the cable wraps therearound to control the torque output of the assembly.
