A dual shaft and rotating machine coupling has a rotor coupling sandwiched between aligned first and second shafts. The first shaft has a first shaft connecting flange radially extending therefrom. The first flange has opposing first axially inner and axially outer surface portions. The rotor coupling has a rotor spider and a rotor connecting flange radially extending from the rotor spider. The rotor flange has opposing first and second surface portions. Coupling studs extend from the first shaft connecting flange through the rotor flange. Each coupling stud has a coupling nut mounted thereon against the second surface portion of the rotor flange to couple the rotor flange to the first shaft connecting flange. The second rotatable shaft has a second shaft connecting flange radially extending therefrom. The second flange has a second axially outer surface portion and a pair of co-planar axially inner surface portions radially spaced from each other by a groove providing a recessed axially inner surface portion spaced from the co-planar surface portions by a predetermined distance. The pair of co-planar axially inner surface portions abut the second surface portion of the rotor flange with the coupling studs passing through the second shaft connecting flange and with the recessed axially inner surfaceportion being spaced to clear the coupling nuts. Additional coupling nuts are each fastened to the coupling studs and against the second axially outer surface portion of the second shaft connecting flange to couple the second shaft connecting flange to the rotor connecting flange.
