1. A gas turbine engine comprising:

  • a rotatable high pressure shaft in driving engagement with at least one high pressure rotor of the engine and having a shaft gear secured thereto;

    a low pressure shaft in driving engagement with at least one low pressure rotor of the engine and rotatable independently of the high pressure shaft;

    an electromechanical device having a rotor and a stator coupled such that the rotor is rotatable with respect to the stator, the rotor having a device gear secured thereto, the device being secured to a support structure in a bearing housing, the bearing housing forming part of a bearing assembly supporting a portion of the low pressure shaft extending in proximity of the high pressure shaft and of the shaft gear; and

    a coupling idle gear secured for rotation about a stationary gear support mounted in the bearing housing, the idle gear being in toothed engagement with the shaft gear and with the device gear.
