Duplicate original class with your new class name DeviceEditorForm with above namespace. replace RenderRenderings method with below code

private void RenderRenderings(DeviceDefinition deviceDefinition, int selectedIndex, int index)
    {
      Assert.ArgumentNotNull((object) deviceDefinition, "deviceDefinition");
      ArrayList renderings = deviceDefinition.Renderings;
      if (renderings == null)
        return;
      foreach (RenderingDefinition rendering in renderings)
      {
        if (rendering.ItemID != null)
        {

          XmlControl webControl = Resource.GetWebControl("DeviceRendering") as XmlControl;
          Assert.IsNotNull((object) webControl, typeof (XmlControl));
          HtmlGenericControl htmlGenericControl1 = new HtmlGenericControl("div");
          htmlGenericControl1.Style.Add("padding", "0");

          string uniqueId = Sitecore.Web.UI.HtmlControls.Control.GetUniqueID("R");
          this.Renderings.Controls.Add((System.Web.UI.Control) htmlGenericControl1);
          htmlGenericControl1.ID = Sitecore.Web.UI.HtmlControls.Control.GetUniqueID("C");
          webControl["Click"] = (object) ("OnRenderingClick(\"" + (object) index + "\")");

          } 
          if (rendering.Rules != null && !rendering.Rules.IsEmpty)
          {
            int num = rendering.Rules.Elements((XName) "rule").Count<XElement>();
            if (num > 1)
            {
              HtmlGenericControl htmlGenericControl2 = new HtmlGenericControl("span");
              if (num > 9)
                htmlGenericControl2.Attributes["class"] = "scConditionContainer scLongConditionContainer";
              else
                htmlGenericControl2.Attributes["class"] = "scConditionContainer";
              htmlGenericControl2.InnerText = num.ToString();
              htmlGenericControl1.Controls.Add((System.Web.UI.Control) htmlGenericControl2);
            }
          }
          RenderDeviceEditorRenderingPipeline.Run(rendering, webControl, (System.Web.UI.Control) htmlGenericControl1);
          ++index;
        }
      }
    }
