Abstract
The coupling between discrete axially aligned first and second turbine shafts includes a flange on one end of one shaft and a rotor wheel on the other shaft. Holes in axial alignment with one another through the flange and rotor wheel receive fastening elements securing the rotor wheel and flange to one another, thereby securing the shaft sections to one another. The fastening elements engage segments on the side of the rotor wheel remote from the flange to facilitate clamping of the flange and rotor wheel to one another. The segments also include outer arcuate surfaces which form sealing surfaces with radially opposed labyrinth teeth of packing ring segments forming part of the turbine diaphragms.
