Abstract

A clutch and handle for applying rotation to a lockable mechanism is disclosed. In particular, the handle is adapted to prevent damage to the handle or a lockable mechanism when excess pressure or torque is applied to the handle. The torque limiting clutch mechanism limits the torque which can be applied by the handle such as to a lockable mechanism for securing a leaf within a frame. The torque limiting clutch mechanism comprises first and second rotors in confrontation to transmit rotational drive from the handle to the lockable mechanism. The first and second rotors are arranged to slip against each other beyond a maximum transferred torque.
