1. An electrically operated actuator in combination with a dead bolt assembly, the dead bolt assembly comprising a lock having a drive bar and a bolt, the bolt being operably coupled to the drive bar such that rotation of the drive bar extends and retracts the bolt linearly, the actuator comprising:

  • means for rotating the drive bar to extend and retract the bolt;

    means for driving said rotating means, said driving means being responsive to an electrical signal;

    wherein said electrical signal is generated by;

    a wireless transmitter that transmits a request to actuate the actuator;

    a wireless receiver that receives the request to actuate the actuator; and

    a control circuit, operably connected to said wireless receiver, the control circuit providing said electrical signal to said driving means if the request is valid; and

    wherein said rotating means comprises;

    a resilient lever attached to the drive bar, said resilient lever being pivotal about an axis that is coaxial to an axis of rotation of the drive bar; and

    wherein said driving means comprises;

    a motor capable of rotating a threaded rod that extends from said motor;

    a threaded member screwed onto said threaded rod;

    a guide preventing rotation of said threaded member; and

    said threaded member being adapted to frictionally engage and to rotate said resilient lever.
