1. A surgical stapler assembly, comprising: a disposable end effector comprising a distal attachment portion, wherein said distal attachment portion comprises: a lock notch; anda longitudinal guide rail; anda surgical instrument, comprising: a proximal attachment portion structured to receive said distal attachment portion, wherein said distal attachment portion is moveable between a non-inserted position and an inserted position relative to said proximal attachment portion, and wherein said proximal attachment portion comprises a longitudinal guide slot configured to receive said longitudinal guide rail as said distal attachment portion moves between said non-inserted position and said inserted position; anda rotatable collar that is rotatable relative to said proximal attachment portion between a locked position and an unlocked position, wherein said collar is biased toward said locked position and is structured to rotate from said locked position to said unlocked position, wherein said distal attachment portion causes said rotatable collar to rotate from said locked position to said unlocked position when said distal attachment portion moves from said non-inserted position toward said inserted position, and wherein said collar comprises a detent structured to move into said lock notch when said collar rotates from said unlocked position to said locked position and when said distal attachment portion is in said inserted position. 2. The surgical stapler assembly of claim 1, wherein said guide rail and said guide slot are structured to prevent rotation of said distal attachment portion relative to said proximal attachment portion as said distal attachment portion moves between said non-inserted position and said inserted position. 3. The surgical stapler assembly of claim 1, wherein said disposable end effector comprises a firing element, wherein said surgical instrument comprises a firing rod, and wherein said firing rod is coupled to said firing element when said distal attachment portion is in said inserted position. 4. The surgical stapler assembly of claim 3, wherein said distal attachment portion comprises a key, wherein said firing rod comprises a rotator, and wherein said key is structured to engage said rotator as said distal attachment portion moves between said non-inserted position and said inserted position. 5. The surgical stapler assembly of claim 1, further comprising a spring structured to bias said collar toward said locked position. 6. The surgical stapler assembly of claim 1, wherein said disposable end effector further comprises a distal articulation control, wherein said surgical instrument further comprises a proximal articulation control, and wherein said proximal articulation control rotates into engagement with said distal articulation control when said collar rotates from said unlocked position to said locked position and when said distal attachment portion is in said inserted position. 7. A surgical stapler assembly comprising: a disposable end effector comprising a distal attachment portion, wherein said distal attachment portion comprises: a firing element;a lock notch;a key; anda longitudinal guide rail; anda surgical instrument, comprising: a firing rod comprising: a rotator;a proximal attachment portion structured to receive said distal attachment portion, wherein said distal attachment portion is moveable between a non-inserted position and an inserted position relative to said proximal attachment portion, and wherein said proximal attachment portion comprises a longitudinal guide slot configured to receive said longitudinal guide rail as said distal attachment portion moves between said non-inserted position and said inserted position, wherein said guide rail and said guide slot are structured to prevent rotation of said distal attachment portion relative to said proximal attachment portion as said distal attachment portion moves between said non-inserted position and said inserted position, and wherein said firing rod is coupled to said firing element when said distal attachment portion is in said inserted position; anda rotatable collar that is rotatable relative to said proximal attachment portion between a locked position and an unlocked position, wherein said collar is biased toward said locked position and is structured to rotate from said locked position to said unlocked position when said distal attachment portion moves from said non-inserted position toward said inserted position, wherein said collar comprises a detent structured to move into said lock notch when said collar rotates from said unlocked position to said locked position and when said distal attachment portion is in said inserted position, wherein said key is structured to engage said rotator as said distal attachment portion moves between said non-inserted position and said inserted position, wherein said collar comprises a groove engaged with said rotator, and wherein said rotator is structured to rotate said collar to said unlocked position when said key engages said rotator. 8. A surgical stapler assembly, comprising: a disposable end effector comprising a distal attachment portion, wherein said distal attachment portion comprises: a key; anda lock notch;a surgical instrument, comprising: a proximal attachment portion structured to receive said distal attachment portion, wherein said distal attachment portion is moveable along a longitudinal axis relative to said proximal attachment portion between a non-inserted position and an inserted position;a firing rod comprising a rotator, and wherein said key is structured to engage said rotator as said distal attachment portion moves between said non-inserted position and said inserted position; anda rotatable collar that is rotatable relative to said longitudinal axis between a locked position and an unlocked position, wherein a spring is structured to bias said rotatable collar toward said locked position, and wherein said collar comprises: a groove engaged with said rotator, wherein said rotator is structured to rotate said collar to said unlocked position when said key is engaged with said rotator; anda detent structured to move into said lock notch when said collar rotates from said unlocked position to said locked position and when said distal attachment portion is in said inserted position. 9. The surgical stapler assembly of claim 8, wherein said disposable end effector comprises a firing element, and wherein said firing rod is coupled to said firing element when said distal attachment portion is in said inserted position. 10. The surgical stapler assembly of claim 8, further comprising a spring structured to bias said collar toward said locked position. 11. The surgical stapler assembly of claim 8, wherein said distal attachment portion comprises a guide rail, wherein said proximal attachment portion comprises a guide slot, and wherein said guide slot is structured to receive said guide rail as said distal attachment portion moves along said longitudinal axis between said non-inserted position and said inserted position. 12. The surgical stapler assembly of claim 11, wherein said guide rail and said guide slot are structured to prevent rotation of said distal attachment portion relative to said proximal attachment portion as said distal attachment portion moves between said non-inserted position and said inserted position. 13. The surgical stapler assembly of claim 8, wherein said disposable end effector comprises a distal articulation control, wherein said surgical instrument comprises a proximal articulation control, and wherein said proximal articulation control rotates into engagement with said distal articulation control when said collar rotates from said unlocked position to said locked position and when said distal attachment portion is in said inserted position. 14. A surgical instrument system, comprising: a surgical instrument comprising a shaft and a shaft axis;an end effector comprising a connection portion and an end effector axis, wherein said end effector is configured to be assembled to said shaft by aligning said shaft axis with said end effector axis and moving at least one of said shaft and said end effector toward the other without rotating said end effector about said end effector axis or said shaft about said shaft axis; androtatable means for automatically coupling said end effector to said shaft when said connection portion is engaged with said shaft, wherein said rotatable means moves from a locked position to an unlocked position when said connection portion is engaged with said shaft.
