Abstract: An adapter for use in a power system having a first powertrain joined to a second powertrain by a coupling. The adapter may have a generally cylindrical body having a central bore formed therein that is configured to receive a shaft of the first powertrain, and splines formed at an end of the central bore. The adapter may also have a connection keyway formed within an outer annular surface of the generally cylindrical body and configured to receive a key that engages the coupling, and a balancing keyway formed within the outer annular surface of the generally cylindrical body and configured to remain empty to balance the coupling.
