I'll give it a crack, but if history proves correct I've got a >90% chance of being incorrect.
Adverse aileron yaw would only be present during the entry and exit from the turn while the ailerons are displaced, but either way this probably isn't a huge factor in most of the aeroplanes you fly thanks to having either differential or frise ailerons, and due to yawing tendancy created by the aircraft slipping. Once established in the turn, the ailerons are neutral or possibly against the turn to overcome the overbanking tendency; now the horizontal component of lift provides the centripetal (turning) force, and now that the heading of the aircraft is constantly changing, the rudder is required to keep the aircrafts longitudinal axis aligned with the direction of flight.
Confused? I know I am, but I'll blame it on the wine...
