Rotate Player "slowly" towards default rotation. (2D Rigidbody)

Question

Just simple. I have a player controller for my 2d platformer. its just a cube at all. (and it will keep that)

How i can force the Rigidbody2D to everytime try to rotate back to the default rotation? (0, 0, 0, 1).

so it can drop from an edge, and "hang" on them while rotating against the gravity ... hard to explain. Here a visualization of it: what i want

Maybe it gets better. But this is my solution:

         Rigidbody2D rb = GetComponent<Rigidbody2D>();
 
         float forceRotationMultiplicator     = 1.5f;
 
         Vector3 ea = rb.transform.rotation.eulerAngles;
         float posRot = Mathf.Round(ea.z * 100f) / 100f;
         float negRot = (0f - (180f + (360f - posRot))) + 180f;
         float rot = posRot;

         if(posRot > 180f) {
             rot = negRot;
         }

         float rotAbs = Mathf.Abs(rot) / 180f;
 
         float rotForce = -360f * (rot / 360f) * Time.deltaTime * (forceRotationMultiplicator * (5f * rotAbs));
         rb.AddTorque(rotForce, ForceMode2D.Force);
