Abstract
The device allows the shafts 5 and 20 to be coupled together on a trial and error basis, said shafts being recessed relative to the ends of the stationary stators. The shaft ends have splines 6 and 21 and are coupled by means of a sleeve 22. Before coupling, the shafts are reference marked relative to the stationary portion by means of cams 27 (and 36 which is not shown in the figure) which enter a groove 6 in the shaft 5 and in a groove of the sleeve 22. During the coupling operation, the cams are retracted by a part 37 at the end of a rod 34 which bears against the cam support yoke 35 for the cam 36 in the case of the cam 27 and by the end 48 of the body in the case of the cam 36. The bodies are connected together by a coupling sleeve 9.
