Coupling, comprising: an outer housing configured to be coupled to one of a driving element and driven element of a drive train, a hub configured to be coupled to the other of said driving element and driven element of said drive train, an inner space enclosed by the outer housing and the hub, an internal body arranged within said inner space, extending around the hub and being movable relative to the outer housing and the hub in a circumferential direction around the hub, a plurality of first chambers formed between the outer housing and the internal body, a plurality of second chambers formed between the internal body and the hub, first leaf springs arranged in said first chambers, said first leaf springs connecting the outer housing and the internal body and extending 2. radially inwardly from the outer housing towards the internal body and being configured to deform elastically upon relative rotation between the outer housing and the internal body, second leaf springs arranged in said second chambers, said second leaf springs connecting the internal body and the hub and extending radially outwardly from the hub towards the internal body and being configured to deform elastically upon relative rotation between the hub and the internal body, first oil gaps are formed between an inner wall of the outer housing facing radially inwardly and an outer wall of the internal body facing radially outwardly thereby establishing throttled fluid communication between neighbouring first chambers for providing hydraulic damping, second oil gaps are formed between an inner wall of the internal body facing the radially inwardly and an outer wall of the hub facing radially outwardly thereby establishing throttled fluid communication between neighbouring second chambers for providing hydraulic damping, and characterized in that the outer housing is provided with interior protrusions, extending radially inwardly, said interior protrusions being configured to clampingly secure outer end portions of the first leaf springs, and that the outer diameter of the internal body extends radially beyond the largest possible circle radially within the inner ends of said interior protrusions. an outer housing configured to be coupled to one of a driving element and driven element of a drive train, a hub configured to be coupled to the other of said driving element and driven element of said drive train, an inner space enclosed by the outer housing and the hub, an internal body arranged within said inner space, extending around the hub and being movable relative to the outer housing and the hub in a circumferential direction around the hub, a plurality of first chambers formed between the outer housing and the internal body, a plurality of second chambers formed between the internal body and the hub, first leaf springs arranged in said first chambers, said first leaf springs connecting the outer housing and the internal body and extending 2. radially inwardly from the outer housing towards the internal body and being configured to deform elastically upon relative rotation between the outer housing and the internal body, second leaf springs arranged in said second chambers, said second leaf springs connecting the internal body and the hub and extending radially outwardly from the hub towards the internal body and being configured to deform elastically upon relative rotation between the hub and the internal body, first oil gaps are formed between an inner wall of the outer housing facing radially inwardly and an outer wall of the internal body facing radially outwardly thereby establishing throttled fluid communication between neighbouring first chambers for providing hydraulic damping, second oil gaps are formed between an inner wall of the internal body facing the radially inwardly and an outer wall of the hub facing radially outwardly thereby establishing throttled fluid communication between neighbouring second chambers for providing hydraulic damping, and characterized in that the outer housing is provided with interior protrusions, extending radially inwardly, said interior protrusions being configured to clampingly secure outer end portions of the first leaf springs, and that the outer diameter of the internal body extends radially beyond the largest possible circle radially within the inner ends of said interior protrusions.
