I think most has been covered - max turbulence penetration speed, don't fight it, etc. Just wanted to add something I learnt very early on in my flying. I had a great old instructor who was always very relaxed (those from Camden probably remember Raoul). On this particular day I was doing circuits in a C152 in quite strong turbulence. I was getting the white knuckle syndrome from fighting it and holding on too tight. We were on a very bumpy final approach when he finally got sick of me fighting, lent over, slapped me on the wrist and said "let it go - it will do a much better job than you are". I did let go and things smoothed out !! never forgotten that.
While not quite the same as what you are talking about it shows that most naturally stable aircraft will fly themselves reasonably well and only need guiding.
