A torque bias coil spring (68,268,268',268",268"') for a camshaft phaser (16,216) disposed on the outside of a cover plate (36,236) for the rotor chamber (35) and connected between the stator (34,234) and rotor (40,240) for angularly biasing the rotor. A rotor extension (64,248), such as a sleeve for a locking pin mechanism (45) or a target wheel unit (250), extends from the rotor chamber (35) through an opening (66,237) in the cover plate for engaging a first spring tang (84,284). The second tang (88,288) of the spring is engaged by a phaser binder bolt (31,231). The spring thus is able to follow the rotary motion of the rotor within the rotor chamber and to bias the rotor toward a predetermined rotational extreme.
