ABSTRACT:
A shear sleeve having a shearing zone of reduced cross-sectional area is fixed at the roll end portion of the shaft of a spindle coupling. The sleeve carries means coacting with a roll end sleeve for rotating it and the shaft. Mating surfaces of the shear sleeve and shaft are in contact during normal operation to prevent bending of the shear sleeve. When the shear sleeve shears under excessive torsional stress the surfaces separate and one end of the shear sleeve rotates freely on a bearing, or bearings, mounted on the shaft.
