Abstract
A single piece coupling for shafts comprises opposite half sections each with an arcuate recess for engaging one side of two axially aligned shafts. There are also spaces forming a keyway for reception of a conventional key with which the shafts are provided. The half sections are initially formed in a spread apart condition with captive edges secured to each other by a section of the coupling metal forming thereby a hinge. After adjacent ends of the shafts are slid into the coupling to abutting positions free edges of the half sections are bolted together drawing the half sections simultaneously into engagement with the shafts and the key.
