A surgical instrument assembly comprising a proximal shaft assembly comprising a proximal drive member and a distal shaft assembly attachable to and detachable from the proximal shaft assembly is disclosed. The distal shaft assembly comprises a distal drive member configured to be coupled to and decoupled from the proximal drive member, wherein the distal drive member is configured to be actuated through a drive stroke by the proximal drive member. The drive stroke comprises a beginning of stroke position, an end of stroke position distal to the beginning of stroke position, and a home position. The proximal drive member and the distal drive member are configured to be coupled to and decoupled from each other when the proximal drive member and the distal drive member are in the home position, wherein the home position is not at the beginning of stroke position or the end of stroke position.
