1. An interface module for selective coupling between an electromechanical robotic surgical instrument and an instrument drive unit, the interface module comprising:
a collar configured to be coupled to the instrument drive unit;
a button supported by and movably coupled to the collar;
a drive transfer assembly including:
a distal end portion configured to couple to a driven member of the electromechanical robotic surgical instrument; and
a proximal end portion movably coupled to the distal end portion and configured to selectively couple to a drive member of the instrument drive unit, wherein the proximal end portion of the drive transfer assembly is configured to move distally, in response to an actuation of the button, to disengage from the drive member of the instrument drive unit; and
a gear selectively engageable with the distal end portion of the drive transfer assembly and manually rotatable to rotate the distal end portion of the drive transfer assembly when the drive transfer assembly is disengaged from the drive member of the instrument drive unit.
