An actuator has a rotatable input member coupled to a drive member such that rotation of the rotatable input member under an input load causes rotation of the drive member on a first axis. The drive member is coupled to a driven member such that rotation of the drive member causes rotation of the driven member on a second axis which is laterally offset from the first axis. A coupling between the drive member and the driven member is arranged to provide a rotational reduction from the drive member to the driven member. The driven member is arranged for connection to a wire of a Bowden cable having a sleeve seatable in relation to a housing for the actuator such that rotation of the driven member causes extension or retraction of the cable. The braking means exerts a braking load on a braking surface of the actuator which is fixed relative to the housing and the braking means is arranged for cooperation with the drive member such that when a backdriving load is exerted through the Bowden cable wire to the driven member, tending to cause the driven member to rotate the drive member, the drive member cooperates with the braking means to increase the braking load to resist rotation of the drive member.
