The adapter assembly (200) selectively interconnects a loading unit (300) and a device housing, and includes at least one drive converter assembly (240) for interconnecting a rotatable drive shaft (122) and an axially translatable drive member (360) of the loading unit (300). The at least one drive converter assembly (240) converts and transmits a rotation of the rotatable drive shaft (122) to an axial translation of the axially translatable drive member (360) of the loading unit (300). The at least one drive converter assembly (240) includes a drive element (212), a drive nut (260), and a distal drive member (248). The drive element (212) defines a longitudinal axis. The drive nut (260) is disposed about the longitudinal axis, and the distal drive member (248) is disposed along the longitudinal axis.1119 clco - C,) 0" CD0
