A steering apparatus (10) for turning steerable wheels of a vehicle in response to rotation of a vehicle steering wheel (12) comprises a first assembly (16), a second assembly (26), and a mechanism (108). The first assembly (16) is operatively coupled to the steering wheel (12) and includes components (18 and 22) for monitoring applied torque and angular rotation of the steering wheel. The second assembly (26) includes a steering gear (34) and components (28 and 30) for receiving the first signal and actuating the steering gear (34) in response to the first signal. The mechanism (108) when in a first mode of operation provides a mechanical connection between the steering wheel (12) and the steering gear (34). When the mechanism (108) is in the second mode of operation, the steering wheel (12) and the steering gear (34) lack a mechanical connection.
