1. An adapter assembly for a surgical device, the adapter assembly comprising:
a connector assembly configured for releasable connection to an actuation device;
a drive transfer assembly operably received through the connector assembly and including a first rotatable shaft and a second rotatable shaft;
a handle assembly rotatably supported on the connector assembly;
an elongate body extending from and rotationally fixed to the handle assembly, the elongate body defining a longitudinal axis;
a first pusher assembly supported within the elongate body and operably connected to the first rotatable shaft for converting rotational motion from the first rotatable shaft to longitudinal movement to perform a first function; and
a second pusher assembly supported within the elongate body and operably connected to the second rotatable shaft for converting rotational motion from the second rotatable shaft to longitudinal movement to perform a second function, wherein:
the second pusher assembly is located distal of the first pusher assembly;
each of the first pusher assembly and the second pusher assembly are located along a common longitudinal axis; and
the common longitudinal axis of the first pusher assembly and the second pusher assembly is coaxial with the longitudinal axis of the elongate body.
