A coupling assembly for connecting a drive shaft in axial alignment with a motor shaft includes a coupling sleeve configured to engage an end portion of each of the motor shaft and the drive shaft. The coupling sleeve extends in the axial direction from a forward end proximate to the motor to a distal rearward end which is remote therefrom. A central bore extends through the coupling sleeve and includes a first end portion extending into the forward end of the sleeve having a size complementary to that of the end portion of the motor shaft. A second other end portion of the bore extends axially into the rearward end of the sleeve and has a size which is complementary to that of an end portion of the drive shaft. The sleeve is secured to the motor shaft and a jack or lifting ring is coupled to the drive shaft adjacent to the sleeve. The lifting ring includes an aperture sized to receive therein a connector which is movable into engagement with the coupling sleeve. An internally threaded bore which is spaced radially outwardly from the central bore is provided in the rearward end of the coupling jacket. The aperture is positioned such that the connector is insertable axially into the threaded bore, whereby engagement of the connector with the internal threads moves the lifting ring and drive shaft along the axis relative to the coupling sleeve and motor shaft.
