1. A surgical instrument system, comprising:

  • a first component, comprising;

    a first shaft portion;

    a first drive portion;

    a first connection portion comprising a bayonet connection; and

    an indicator adjacent said bayonet connection;

    a second component comprising a second shaft portion, a second drive portion, and a second connection portion, wherein said second connection portion is engageable with said first connection portion, wherein relative rotational motion between said bayonet connection and said second connection portion rotatably connects said second component to said first component and rotatably connects said first drive portion and said second drive portion;

    a motor configured to apply a drive force to said second drive portion; and

    a controller configured to detect whether said second component is properly connected to said first component, wherein said controller is responsive to a first set of operating instructions when said controller detects that said second component is properly connected to said first component and identifies said second component, wherein said controller is configured to activate said indicator when said controller detects that said second component is not identified by said controller, and wherein said controller is responsive to a second set of operating instructions when said controller does not identify said second component in order to limit the drive force that said motor can apply to said second drive portion to perform a firing motion.
