1. A replaceable surgical stapling loading unit attachable to and detachable from an attachment interface, wherein said replaceable surgical stapling loading unit comprises:

(a) a shaft, comprising:

(1) a plurality of actuators, comprising

an output firing actuator couplable to a firing drive of the attachment interface; and

(2) a proximal bayonet attachment portion configured to be attached to the attachment interface by way of a twisting motion to couple said actuators to the firing drive and the articulation drive;

(b) an actuated member movably supported on said shaft and configured to engage the attachment interface, wherein said actuated member is configured to be longitudinally fixed relative to said shaft and said shaft is rotatable relative to said actuated member during said proximal bayonet attachment portion being attached to the attachment interface, and wherein a position of said actuated member indicates the attachment of said proximal bayonet attachment portion to the attachment interface;

(d) an end effector assembly articulatable relative to said shaft by way of said articulation joint, wherein said end effector comprises:

(1) a first jaw;

(2) a second jaw movable relative to said first jaw;

(3) an anvil; and

(4) a staple cartridge comprising a plurality of staples configured to be deployed against said anvil during a staple firing stroke, wherein said output firing actuator is actuatable to move said second jaw relative to said first jaw and to deploy said staples from said staple cartridge during said staple firing stroke.
