There is provided an electricity generating device comprising a housing (10); a first lobed rotor (21) and a second lobed rotor (22) rotatably arranged in a fluid passage enclosed by the housing (10) such that the lobes of the first (21) and the second lobed rotor (22) intermesh to create a barrier between a high-pressure and a low- pressure side of the housing (10) during operation of the device; a first electricity generator (25) to which the first lobed rotor (21) is coupled, the first electricity generator (25) being capable of varying the load of the first lobed rotor (21); and a second electricity generator (26) to which the second lobed rotor (22) is coupled, the second electricity generator (26) being capable of varying the load of the second lobed rotor (22). There is also provided a method of synchronizing rotational positions of a first lobed rotor (21) coupled to a first electricity generator (25) and a second lobed rotor (22) connected to a second electricity generator (26) in a turbine, said first and second lobed rotors (21, 22) being intermeshed, comprising controlling the first and/or the second generator (25, 26) to adjust a rotational position of the first lobed rotor relative a rotational position of the second lobed rotor to avoid contact between the intermeshing lobes of the first and the second lobed rotors.
