1. A surgical fastening apparatus, comprising:

  • an end effector comprising a firing member, wherein said firing member is movable between a starting position and an ending position within said end effector;

    a rotary drive shaft operably interfacing with said movable firing member such that rotation of said rotary drive shaft in a first rotary output direction causes said movable firing member to linearly advance in a distal direction within said end effector and rotation of said rotary drive shaft in a second rotary output direction causes said movable firing member to linearly retract in a proximal direction within said end effector;

    a motor mechanically coupleable with said rotary drive shaft such that operation of said motor in a first rotary input direction causes said rotary drive shaft to rotate in said first rotary output direction and operation of said motor in a second rotary input direction causes said rotary drive shaft to rotate in said second rotary output direction; and

    a manually actuatable bailout system configured to selectively mechanically decouple said motor from said rotary drive shaft and manually apply rotary control motions to said rotary drive shaft in said second rotary output direction.
