Zusammenfassung:	A surgical robot arm comprising a terminal link 504 with a drive assembly interface comprising drive assembly interface elements 1101a-c. Each drive assembly interface element is configured to engage an instrument interface element 901a-c of an instrument interface 302 of a robotic surgical instrument when the surgical robot arm engages the robotic surgical instrument; and move relative to the drive assembly interface across a range of motion so as to, when engaged with the instrument interface element, transfer drive to that instrument interface element. The drive assembly interface elements are arranged across a plane perpendicular to the longitudinal axis of the terminal link such that the robotic surgical instrument is detachable from the surgical robot arm in a detachment direction parallel to the plane, wherein each drive assembly interface element is configured to move relative to the drive assembly interface in a direction perpendicular to the longitudinal axis of the terminal link.
