Yaw Dampener: Pilot rudder input

[jpilotj]

Good day,

I recently read in the King Air magazine that gets delivered to my place of work that the Yaw Dampener is often mistaken as a device that omits the requirement for pilot rudder input (i.e the assumption is that the yaw dampener will always create a co-ordinated turn by the virtue of it cancelling any yaw). As the article stated however, this is not the function of the yaw dampener in entirety and input is still required to co-ordinate a turn, skid or slip condition.
I am therefore wondering what the requirement for rudder input is in larger jet aircraft. With the rudder being hardly ever used in flight in most normal circumstances is it the yaw dampener co-ordinating all turns?
If the yaw dampener is co-ordinating turns, why then does the normal axis remain at the pilots control with the auto pilot engaged. From my understanding the autopilot normal axis only activates on auto lands.

Thank you,
