A buckling prevention device including a first rotational element, a second rotational element, a leaf spring arranged for transferring torque between the first and second rotational elements while enabling relative axial movement between the first rotational element and the second rotational element, a connection member fixedly connecting the leaf spring to the second rotational element, wherein the connection member extends axially through a hole in the first rotational element, wherein a gap is formed between the connection member and an edge of the hole when the leaf spring is not experiencing an overly high compression force, and wherein the connection member is operatively arranged to close the gap and engage with the first member when the spring is experiencing an overly high compression force for preventing the leaf spring from buckling and at least partially transferring the torque directly between the first and second rotational elements.
