Manouveing speed is the speed at which naximium deflection of controls will not 
cause unsafe stress on the airframe. It is irrelevant whether such movement 
comes from the autopilot or a pilots own hands.  Further autopilot servos have 
slipping clutches and shear pins designed into them to prevent undue stress on 
airframes at higher speeds. This factor also allows the pilot to override them 
at any time without damage as a further safety step. Most older autopilots 
still in use today do not use attitude as a reference. They are rate based. An 
example is the STEC series, a system that has been used safely for years. It is 
only more recently that digital attitude based systems have become available 
and it not essential to have one. Autopilots have dampening mechanisms to 
reduce scalloping or chasing the wing dip or nav/gps needle. In extreme 
turbulence the autopilot cannot respond quickly enough sometimes and it is for 
this reason  that it is recommended it be disconnected. It has very little to 
do with stressing the airframe especially at manoueving speed or less.
