The driver includes a first driving member and a second driving member axially aligned with the first driving member and nonrotatably coupled to the first driving member, wherein the slave is at least partially disposed within the second driving member. At least one of the first driving member and the second driving member define a housing space, and a power transmitting mechanism is disposed at least partially in the housing space for changing a rotational speed of the driver and for communicating rotational power from the driver to the slave.
