A steering column assembly comprises an adjustable steering column (1) adapted to pivot about a point along its length relative to a mounting bracket (6). The steering column assembly also includes a gearbox adapted to transfer torque generated by an electric motor to the steering column (1). A spring (9), between the steering column (1) and the bracket (6), applies a twisting force sufficient to take up any radial play at the pivot. The spring (9) may be offset radially from the axis of the pivot in a direction parallel to the steering column axis as well as laterally offset from the axis of the steering column (1). An advantage is that the spring (9) eliminates vibration in the steering column (1) due to reaction torque from the electric motor, and can also act as a counter-balance to the weight of the electric motor.
