1. A surgical instrument, comprising:

  • a surgical end effector;

    a threaded rotary input shaft;

    an actuator member in operable engagement with said surgical end effector and selective threaded engagement with said threaded rotary input shaft such that when said actuator member is in an engaged configuration, said actuator member is in threaded engagement with said threaded rotary input shaft such that rotation of said threaded rotary input shaft causes said actuator member to move axially to impart an actuation motion to said surgical end effector and when said actuator member is in a disengaged configuration, rotation of said threaded rotary input shaft will not be imparted to said actuator member;

    means for selectively moving said actuator between said engaged and disengaged configurations; and

    a locking system for preventing axial movement of said actuator member when said actuator member is in said disengaged configuration.
