A transmission having an inner rotationally mounted shaft (42) with first and second parts (44and 46) and an outer concentric rotationally mounted shaft (49) in accordance with the invention includes a clutch (48) connected to the first and second parts of the inner shaft, which is movable between a first engaged position in which torque may be transmitted through the clutch between the first and second parts and a second position in which torque is not transmitted through the clutch; a transmission, coupling one of the parts of the inner shaft to the outer shaft to transmit torque from the inner shaft to the outer shaft when the inner shaft is rotating; an axially movable mechanism (61-80) disposed outside of and concentric with the outer shaft and projecting through the outer shaft for engaging one of the parts of the inner shaft to move the one part between first and second positions, the axially movable mechanism being movable between first and second positions to cause the one of the parts of the inner shaft to move axially between the first and second positions to move the clutch respectively between the first and second positions to control the transmission of torque between the parts of the inner shaft.
