Actually my simmechanics stewart platform model works great and below you can se rotation around z-axis(yaw). Just one problem is spherical joints turning and moving independently which is not effecting moving trajectory but demonstration is little bit disturbing for formal presentation.How can i solve this problem?
Thank you for any suggestion.

ı'am used rotational hard stop on spherical joints x and z axis after posting this and limit the rotation angle but my desire actually is not just limiting the rotation angle also avoid non necessary movement, currently problem solved but still can not give me realistic behavior.Is there any other good way to solve this issue with more realistic solution?

I believe based on the image you can replace the spherical joints with universal joints at the top and bottom (or even just at the top) and you will get the motion you need. This will prevent the legs from spinning about their longest axis.
