A clutch for preventing overloading of a mechanism which adjusts headlamps in a vehicle. A worm gear or driven gear is driven by a worm or driving gear mounted on a flexible shaft. The worm gear or driven gear adjusts a headlamp reflector in one embodiment. When the worm gear or driven gear reaches a limit of rotation, the flexible shaft deflects, thereby causing the worm or driving gear to disengage from the worm gear or driven gear, thereby preventing further rotation of the worm gear or driven gear and possible damage thereto or to other components of the system.
