The adapter assembly (100) includes an actuation shaft (132) configured to convert rotation of a first drive shaft (116) of the powered actuator device (20) into an axial translation of a first drive member of the surgical end effector (40, 50, 60, 70). The adapter assembly (100) further includes an elongate tube (142) configured to convert io rotation of a second drive shaft (118) of the powered actuator device (20) into an axial translation of a second drive member of the surgical end effector (40, 50, 60, 70). The actuation shaft (132) is disposed within the elongate tube (142), and the actuation shaft (132) and the elongate tube (142) translate axially independent of each other.
