1. A device for orienting a load, with which is associated an orthonormal device reference frame XYZ, with centre 0, the orientation device being intended to orient said load about a longitudinal axis X, called main axis, and a transverse axis Y, called secondary axis, the orientation device including:
a first shaft, called transmission shaft, intended to support said load, configured to be rotated, at centre 0, about the main axis X and the secondary axis Y,
a second shaft, configured to be rotated about the main axis X,
a third shaft configured to be rotated about a third axis of rotation, in the same direction as the main axis X,
a first connection component between the transmission shaft and the second shaft, configured to prevent relative movements between said transmission shaft and said second shaft in, both a degree of rotational freedom about the main axis and three degrees of translational freedom,
a second connection component between the transmission shaft and the third shaft and configured to allow relative movements between said transmission shaft and said third shaft in both a degree of translational freedom along the third axis of rotation and three degrees of rotational freedom,
the second connection component, the transmission shaft and the third shaft forming an eccentric kinematic connection.
