The invention relates to a transmission device (1) for hybrid aircraft comprising a turboshaft engine having a gas generator (12), a free turbine (14), and a main rotor (52), the device comprising a first reversible electric motor (30) coupled to a shaft (16) of the free turbine (14) via a first disengageable coupling means (32), and to the main rotor (52), and a second reversible electric motor (40) coupled to a shaft (18) of the gas generator (12) via a second disengageable coupling means (44), and coupled to the main rotor (52) via a third disengageable coupling means (42), the second disengageable coupling means (44) being operable when the second electric motor (40) rotates in a first direction of rotation, and the third disengageable coupling means (42) being operable when the second electric motor (40) rotates in a second direction of rotation opposite to the first direction of rotation.
