A torque transmission device comprising: - a first element which is able to rotate about an axis of rotation (X); - a second element which is able to rotate about the axis of rotation (X); - a third element which is able to rotate about the axis of rotation (X); - a first spring which is arranged between the first element and the third element so as to be compressed elastically upon relative rotation between the first element and the third element , - a second spring which is arranged between the second element and the third element so as to be compressed elastically upon relative rotation between the second element and the third element , the first spring and the second spring being arranged in series between the first element and the second element by way of the torque transfer element of the third element , - a first supporting seat positioned at a first end of the first spring , on the one hand between the first element and the first spring so as to transfer torque between the first element and the first spring in a first direction (S1) of relative rotation of the first element and second element , and, on the other hand, between the second element and the first spring so as to transfer torque between the second element and the first spring in a second direction (S2) of relative rotation of the first element and second element , - a second supporting seat positioned at a first end of the second spring , on the one hand between the second element and the second spring so as to transfer torque between the second element and the second spring in the first direction (S1) of relative rotation of the first element and second element , and, on the other hand, between the first element and the second spring so as to transfer torque between the first element and the second spring in the second direction (S2) of relative rotation of the first element and second element ; the torque transmission device being characterized in that the third element comprises a torque transfer element directly transferring torque between the first spring and the second spring . - a first element which is able to rotate about an axis of rotation (X); - a second element which is able to rotate about the axis of rotation (X); - a third element which is able to rotate about the axis of rotation (X); - a first spring which is arranged between the first element and the third element so as to be compressed elastically upon relative rotation between the first element and the third element , - a second spring which is arranged between the second element and the third element so as to be compressed elastically upon relative rotation between the second element and the third element , the first spring and the second spring being arranged in series between the first element and the second element by way of the torque transfer element of the third element , - a first supporting seat positioned at a first end of the first spring , on the one hand between the first element and the first spring so as to transfer torque between the first element and the first spring in a first direction (S1) of relative rotation of the first element and second element , and, on the other hand, between the second element and the first spring so as to transfer torque between the second element and the first spring in a second direction (S2) of relative rotation of the first element and second element , - a second supporting seat positioned at a first end of the second spring , on the one hand between the second element and the second spring so as to transfer torque between the second element and the second spring in the first direction (S1) of relative rotation of the first element and second element , and, on the other hand, between the first element and the second spring so as to transfer torque between the first element and the second spring in the second direction (S2) of relative rotation of the first element and second element ; <EOS>
