I do it this way:
https://create3000.github.io/x_ite/reference/field-services-and-objects#sfmatrix3dsfmatrix3f-object

With setTransform the rotation parameter is a number value, describing the rotation angle in radians.
With getTransform the rotation is a SFVec3f object, where x, and y are the complex value of the rotation, and the z component is the rotation angle in radians.

Best regards,
Holger
