L'élément de réglage est une broche filetée présentant, au moins partiellement, un filetage. L'élément de réglage présente, comme cavité de positionnement, une rainure périphérique dont la largeur correspond au diamètre extérieur du boulon de centrage plus 50 μm ± 50 μm. L'invention permet ainsi d'obtenir un dispositif de réglage de précision qui, pour un faible encombrement et un faible nombre de composants, est simple, fiable et d'une manipulation ne nécessitant pas une grande dépense d'énergie.
