ABSTRACT:
A device for connecting the ends of two aligned sections of a hollow drive shaft which are rotatable about a common axis has first and second coupling members for securing to the ends of the drive shaft sections. At least two shearable bolts or pins connect the coupling members for transmitting torque between the drive shaft sections during operation and are arranged for balanced rotation of the coupling members under high r.p.m. conditions. The bolts, and not the drive shaft, will shear when the coupling members are subjected to a predetermined overload condition. The coupling members also include an annular groove and a correspondingly shaped annular projection for maintaining the shaft sections in axial alignment upon shearing of the bolts, and a collar for preventing the collapse of the shaft sections by restricting axial movement of the coupling members upon shearing of the bolts.
