BEagle has it spot on although most autopilots will turn at 28º AOB.
In addition, many autopilots will have the facility to selecte a lower bank angle - the B737-200 has the option to set 15º or 20º and the HS125-800 has a "half bank" facility giving 14º. These lower bank angles may be useful at higher altitudes when the IAS is close to the low speed buffet boundary.
Plus, as long as you have a yaw damper you don't need to apply "top" rudder - the pedals become footrests!
