Custom module template override not loaded
I think you are missing the argument for the hook_theme so you can do it this way

/**
* Implements hook_theme().
*/
function lnr_theme($existing, $type, $theme, $path) {
 $items = array();
 $path = $path . '/templates';

 $items['actualite_filter_article'] = array(
  'path' =&gt; $path,
  'template' =&gt; 'actualite-filter-article',
 );

  return $items;
}


Give it a shot
