An improved centrifuge structure is provided for medical diagnostic purposes, and the like, and which is particularly suited for use in conjunction with urine, blood and microhematocrit analyses. The structure involves an electric motor which is supported so that its drive shaft extends upwardly along the central axis of the centrifuge, and a coupler, in accordance with the invention is attached to the shaft by means, for example, of a set screw, or other means. The coupler defines a transverse trough extending radially with respect to the axis of rotation of the drive shaft, and the drive shaft extends upwardly through the bottom of the trough. A mating bushing is attached to the underside of the power head of the centrifuge, and it has a central aperture for receiving the motor shaft. The lower end of the bushing has a configuration which is shaped to fit into the transverse trough of the coupler. A screw extends down through the power head and through the bushing to be threaded into the upper end of the drive shaft.
