Abstract

Various embodiments provide a torque transfer unit for rotating a flexible shaft. The torque transfer unit comprises an elongate track defining a track passage, and a key attachable to the flexible shaft and movable along the track passage. The key and the elongate track are configured to engage each other to inhibit relative rotation of the key and the track passage. The torque transfer unit is actuatable to selectively adjust an axial position of the key relative to the track passage. Some other embodiments provide a kit of parts.
