A high-fidelity mechanical transmission system for transmitting forces which can be used in a human-computer force feedback interface device connected to a host computer. The transmission system includes multiple stages, including an actuator stage coupled to an actuator and one or more additional stages. The actuator stage includes a rotatable capstan pulley coupled to the actuator, a cylindrical capstan drum, and a flexible member, such as a cable, coupling the capstan pulley and drum. The cable is coupled to the capstan drum at both ends, and causes the capstan drum to rotate for multiple revolutions. The output stage is coupled to the driven object to rotate the driven object. The output stage can include a capstan pulley, capstan drum, and cable. An interface device can include the transmission system for inputting motion signals to a connected host computer and for providing force feedback to the user. The interface device includes a user manipulatable object, such a steering wheel, joystick, or the like, which is manipulated by the user to interact with the host computer.
